Aim: The aim of the project is to determine the effects of caffeine on cardiac output. The study will examine the effects of caffeine ingested through a caffeinated sports drink and monitor its effects on blood pressure (BP) and heart rate (HR) before and after exercise. Caffeine is a one of the most frequently consumed drugs in the world. It is estimated that an average person consumes 70 mg per day (1). Caffeine has physiological and psychological effects, predominantly due to the inhibitory effects of adenosine, which acts as an inhibitory neurotransmitter in the central nervous system (2). Adenosine also has vasodilator effects. The consumption of caffeine may increase blood pressure and heart rate by inhibiting vasodilation. There have been numerous studies demonstrating the effects of caffeine on heart rate and blood pressure. This research will aim to understand the effect these substances may have in people who exercise. Caffeine is always a popular topic in the science community. Studies show that there are beneficial effects, however many other studies show that it can have a negative impact. Testing the effects on HR and BP is significant in determining the effect caffeine may have on a person’s health. Introduction: Caffeine is a naturally occurring stimulant drug found in the leaves, seeds, and fruits of certain plants. It acts as a central nervous system stimulant, often used to combat drowsiness and restore alertness. Caffeine works through several mechanisms but its most noted effects are on adenosine. Adenosine is an inhibitory neurotransmitter that disrupts activity in the central nervous system (2). Caffeine is lipid and water-soluble that readily crosses the blood-brain barrier. Once in the brain, caf... ... middle of paper ... ...healthy participants will be enrolled in this study. They will consume 250 mL of energy drink, which is considered the normal serving size of the beverage. Participants must also be physically fit to be able to run the one-kilometer after taking baseline measurements for heart rate and blood pressure. No tests will be completed without the consent of the participant. Relevant: Even though many adverse effects have been demonstrated, the consumption of caffeinated sports drinks is growing each year. The use in sport is growing as well, especially among younger populations. There are reports frequently that link energy drink use with conditions that include heart palpations and insomnia, however these warning seem to be ignored. With the growing use it has become important to identify the potential risk that caffeinated sports drinks may have on the population.
